BARREL-PAINTING MACHINE.

Application filed November 24, 1920. Serial No. 426,215.

To all whom it my concern:

Be it known that I, FRED C. FANTZ, a citizen ot' the United States, residing in Port Arthur, inthe county of J eiferson and State of Texas, have invented certain new and useful Improvements in Barrel-Painting Machinespof which the following is a specification.

This invention relates to apparatus for painting or applying liquid coatings to barrels, casks and similar articles.

One object of the invention is to provid a durable and efficient mechanism that is power operated and capable of painting barrels in large quantities in a continuous and rapid manner.

Another object of the invention is to provide suitable .elevating mechanism whereby the barrels, after havlng been painted may be discharged inan upright position in orderthat the paintedv surfaces may not be soiled or disigured while vbeing conveyed from the apparatus. f

Other objects and advantages of my invention will become apparent from the following detailed description thereof.

Referring' ,to the drawings:

Figure 1 is a side elevation of an apparatus arranged in accordance with the invention and constituting an embodiment thereof.

' Figure 2 is a planv View taken on the line 2 2 of Figure 4.

Figure 3 is a sectional lelevation taken on the line 3 3 of,-Figure 2.

Figurev 8 is alongitudinal section taken on the line 8 8 of Figure 7 but drawn to a Ylar er scale.

igure 9 is a view in detail of a movablev sprayer member.

Figure lO-is across section of the sprayer takenon'the line 10 10 of'Figure 9.

In the drawings like arts are designated by the same reference c aracter throughout all the gures'.

The apparatus requires suitable support- -the construction of a nspraying means for ing perforations.

re 4 is a sectional elevation taken onv neath the barrel in its position during the painting .operation is a paint pan 13. The pan may. be formed with an inclinedl bottom, as 1llustrated, and a suction pipe 14 -connected to a pump 15 is arranged to withdraw liquid from the pan. The pump has an otlet line 16 whicli is adapted to conduct paint to the spraying mechanism. The pipe 16 preferably terminates in a lurality of branch lines 17 through which t e paint enters the spray pipe 18. The pump may also have a branch line 16a leading to a suitable source of paint. Any suitable spray pipe may be employed in carrying out the invention. Diiculty has, however, been experienced in the past in paint'that will notl clog up due to the partial drying ofthe paint,Y the presence of flaky materials in the paint and sometimes foreignsubstances that tend to seal the spray-A I have designed a novel form of construction by which these difculties have been obviated, the mechanism comprising a spray pipe having'hinge connected sectionswhich when open enables the piper` to be flushed andthe perforations kept 90 clean.

In the type of construction illustrated in detail in Figures 9 and 10 the sprayer hasy a base plate 19 to one side of which is rigidly -secured a plate 20.A At each end are plates 21 anda movable plate 22 is pivotally supported on pins 23. The base plate preferably contains a `groove filled with a suitable' packing material 24 .which vseals the joint between the parts. Theupper portions of the plates are curved inwardly so that the edges meet, as clearly shown in Figure 10., Along the line of vContact a plurality of pairs ofperforations in the form of contiguous'half circles 25 are provided so as to form circular opening'sfor the, sprayer when the movable plate 22 is movedv to a closed position. An operating lever-26 is clearly shown in Figure 2, is connected by ylinks 27 vand 28 to the foot lever 29.

The movement of the lever 26 govern the size of the discharge openings and controls the force with which the paint is sprayed onto the barrel; Thus if the operator closes the plate 24 tightly'the paint will be discharged through the perforations with considerable force but if he close it only partially the flow of paint will be more sluggish. The lever 26 also enables the regulation of the length of time the paintis applied to the barrel, the arrangement shown allowingthe operator to stop the flow paint against the barrelas soon as sufficient coating has been ap lied, since when the sprayer is opened su ciently, although the paint will continue to flow from the pump, it will cease to be sprayed against the barrel. During .the period between the actual painting of the barrels the sprayer remains open and the paint is -allowed to flow over the perforations thus freeing them from any obstructions and keeping them clean.

A driving shaft 30 is rotated by a sprocket wheel 32 and is mounted upon the frame 11 in bearings 31. A frame 33 is suitably disposed over the paint pan 13 and is hinged upon the shaft 30, by bearings 34, the sha-ft .acting as a pivot about which the 'frame may be swung. AThe frame supports a pair of shafts 35 upon which are mounted a plurality of wheels 36 which are preferably notched or corrugated in order to give them goodA contact with the barrel. The shafts 35 are driven by the shaft- 30 through the gears 37, the arrangement being such as to allow the free swinging movementof the frame. A

The frame 33 constitutes a support upon l which the barrel rests while being painted.

the wheels 36 operating to rotate the barrel during the painting. It also constitutes a carriage -by which the paintedv barrel is raised from a horizontalto an upright position and deposited upon the guide members 39 and conveyor 38.-

The frame4 33 is provided with suitable elevating mechanism such as a air of chains vor cables 40 secured to the ca le drum 41,

and so attached to the carriage 33 that it may be raised and lowered or.swung on its pivot. Each cable is preferably fastened to the side of the carriage opposite the pivot side and the cables' are guided by upright guide members 42 which keep the cables laway from the barrel.

Referring now to Figure 8l it will be seen that the cable drum 41 is carried on a shaft 45 to which-it is rigidly secured. The

' shaft is supported by a pair of the up- 1rights 12 in a bearing 46,' and stationary nut bearing 47 which is engaged by a rotatively adjustable screw threaded sleeve The engaging screw`48 is operated by a i lever 52 by appropriate movements of which the shaft is shifted so that the clutch member 51 is moved into engagement with the cooperating member 50 and thus causes the drum 41 to rotate. The lever 52 also serves to release the clutch when it is desired t0 stop the'rotationvof the drum 41. The spring 53 serves to facilitate the disengagement of the clutch members uponra releasing ofthe clutch. provided with guides 54 for the cables 40.

The carriage 33 is provided vwith an additional cable 55 swung over the pulley 56 and carrying a weight 57. The Weighted cable The drum may be side of the carriage opposite the pivot side and serves as a. means of initiating or accel erating-t-he return movementof the carriage from the discharge position to the painting position and serves also as la cushioning or retarding means functioning to diminish the speed and force of the fall during the latter part of the return movement.

Brushes 58 are disposed preferably underneath the barrel and in close proximity to the sprayer 18. To obtain the best results the brushes are arranged to readily adapt themselves to the contour of a barrel and may be placed in staggered formation in order that the brushes may overlap. In the form of construction illustrated each brush is secured to a lever 59 which is pivotally supported upon a rod 60. A weight 61 is7 placed at the end of each lever 59, opposite from that to which the brush is attached and tends to hold the brush against the surface of the barrel. Thus the brushes are readily adapted to press against the barrels regard less of variations in size, shape and contour.

A control rod 62 may be provided by which i -end 'of lever 59 at a higher level thus pre-' venting excessive friction on the brushes In other words, the rod 62 operates to limit or confine the movement of` the brushes ywithin certain limits.

As there may be more or less dirt, shavings, sawdust, etc., rubbed oil' from the bar rel's during the painting operation a screen 63 may be provided which will tend to keepv the foreign particles on that side of the paint pan opposite the draw-off pipe 14. If desired a horizontally disposed screen may be used to keep the foreign matters from collecting in the paint pan. For example, :1 screen may be laid over the brush levers 59. As hereinbefore stated the apparatus is designed to be power operated and in the arrangement illustrated power is supplied to the various parts of the. apparatus by the motor 64 which operates the main gear 65 upon the shaft 66. The shaft 66 also carries a sprocket wheel 67 by which power is transmitted through the chain 68 to the sprocket 49 which rotates on the shaft 45, the sprocket 32 on the shaft 3() and the sprocket 69 which operates the pump 15.

In operation the barrel to be painted is taken from a suitable runway 70 from the l position A and is rolled onto the carriage 33 into position B. The motor is kept running and consequently the barrel is rotated by the wheels 36. The sprayer 18 .is normally open in order that theflow of paint may keep itushed out. But when a barrel is in position for painting the operator closes the sprayer by means of the lever 26 so that the paint is forced outthrough the perforations 25 and aga-inst the surfaceof the barrel. As the barre-l rotates the spray of liquid and the action of the Vbrushes operate to thoroughly coat the barrel surface. The operator then opens the spray pipe so that the paint will cease to strike against the barrel. He may allow. the banrel to be' rotated for a short time after the spraying has ceased in order that excess pain-t `may be removed from the Vbarrel surface by the brushes 58. He then throws in the clutch by means of lever 52 which causes the drum 41 to rotate and wind up the chain or cable 40. This raises the carriage 33 and elevates the barrel into the discharge or an upright position C as shown in'Figure 3. The clutch may then be released with the barrel thus resting upon the discharge skids- 39 Athe weight of the barrel serving to prevent the carriage 33 from dropping back intothe painting position B. When, however, the barrel has been removed from the members 39 by means of the conveyer 38 the carriage- "forms an angle at 564 greater than 45 and consequently uponthe removal of the weight of the barrel from the skids 39 the weighted cable exerts a pull on the carriage, the weight 57 descending from position lC1 to position D1. Whenthe angle made by the cable at 56 has been reduced to about 45 it is obvious that the downward movement of the weight will cease and that the cable will no longer exert a pulling force upon the- 4carriage 33. As the carriage continues its return movement the angle at 56 decreases while at the same time excessive wear ofthe mechanism is avoided.

In the practice of my invention barrels may be coated or painted thoroughly and at the same time rapidly and with aminimum amount of paint. There is' no loss of paint as the operation is carried on over the paint pan and any excess paint sprayed onto the barrel is removed by the brushes and drops into the pan. After being painted the barrel is discharged in an upright position and thus it is not disfigured or soiled by being'rolled. The continuity of my system is another distinct advantage inasmuchV as the machine' may be voperated continuously without being interrupted for repairs or cleaning, the arrangement provided for preventing the sprayer from becoming clogged up contributing especially to this desirable result. c

It will be obvious to those skilled in the art that various modifications in mechanical structure may be made in the apparatus shown and described in detail herein without departing from the spirit of the'invention the scope of which isset forthin the appended claims.
